How green cities could remove CO2 from the atmosphere

One gigatonne per year by mid-century: An study determines the potentials, various co-benefits and possible barriers to implementation

06-May-2024 - More than a thousand cities around the world now have “net zero” pledges: they want to emit only as much CO2 into the atmosphere as they can simultaneously recapture. An elaborate meta-study has now summarised the state of knowledge on which methods might be useful and what they could achieve. ...
